This invention relates to Aa rocking-chair of that class in which the seatis pivoted to a supporting-frame, and

'held in front andrearby a spring or springs.

The invention consists inconnecting the apparatus `with a `-rotary fan on the backof the` chair, so that said A, in thedrawin represents the support of the chain; i

"B is one side bar` ofthe chair-seat; O,the other.

These side barsare connected bysuitable cross-bars a, and by a bottom of suitable construction7 and carry also 4theside `pieces `of thechair-back D, as shown.

. f Theseat is, bymeansofa ypin', b, passinguthrough lugs c of the, seat" into a projection, d, of4 the support, or otherwise, pivoted to thel latter, and canbe oscillated on the pin b, oritsequivaleut. l

. "A spring or springs, e, ac ng 1n front and rear of the f pivot, against the under side of the seat, give to the rocking motion the requisite elasticity.

J For `this purposea simpleilat spring, e', may be em-` ployed, whichis fastened tothe' projection 0f the fan will be set in niotionand revolved wheneverthe:`

support, and reaches forward and `backward of the Same.

Y To each sidebar of the seatis pivoted a lever, E, which is. by` a rod, f, connected with thelcrank-axle g 4liront end of said lever, will come under one of the `springs e. j

,"The pivotof the lever E of the bar C, is, as in lig. 2,

`on the front end of the same, so that the pin will be i near the middle ofthe saule.

The two'levers will thus, as the chairis 'rocked on the pin b, swing on their centres h, in opposite'direca` tions, one moving up whenrthe other goes down; thus the requisite rotary motion is imparted to the .fau by the oscillating motion 'of the chair. L

Having thns'describcd my invention, l

What I clairnas new, and desireto secure by Let- 'ters Patent,I isi 1. The levers E E, pivoted to the side bars of the4 swinging seat, andconnected withthe rotary fan, as i described, they being so hung that they will swing in opposite directions, substantially as herein shown and described. A .y

l 2. 'lihe combination of the support A, which carries the pivoted seat, with the springs e, levers E, rods f,

and rotary fail F, all arranged and operatngrsubstantially as herein shown fand described.
